Answer the following case study (retrieved from Project Management: A Systems Approach to Planning, Scheduling, and Controlling):
Your manufacturing team informs you that they have found a way to increase the size of the manufacturing run from 10,000 to 18,000 units in increments of 2,000 units. However, the setup cost will be $150,000 and the defects will cost the same $120 for removal and repair.
1. Calculate the economic feasibility of make or buy.
2. Should the probability of defects change if we produce 18,000 units as opposed to 10,000 units?
3. Would your answer to question 1 change if the company management believes that follow-on contracts will be forthcoming? What would happen if the probability of defects changes to 15 percent, 25 percent, 40 percent, 15 percent, and 5 percent due to learning-curve efficiencies?
